Objective To investigate the value of partial hepatectomy in the treatment of hilar cholangiocarcinama( HCC). Methods In this report, 42 patients with hilar cholangiocacinoma treated surgically were analyzed retrospectively. Results Of the 42 patients, 34 cases (81%) underwent surgical resection. In these 34 cases, 15 cases were treated by local resection, 8 cases by a combination of right lobectomy, 3 cases by left lobectomy, 4 cases by left lobectomy and caudate lobectomy, 1 case by left lateral lobectomy and caudate lobectomy, 3 cases by quadrate lobectomy. Curative resection was performed in 25 patients. The median survival rate in patients with curative resection was 28 months, while that with palliative operation was 14 months. The 1-, 2-, and 4-year survival rates of curative resection were 90% , 73% , and 28% , respectively. The 1-, and 2-year survival rates of palliative operation were 57% , and 27%. Conclusion Survival rates in patients with curative resection were better than that of palliative operation. Radical resection in many cases demands a combined liver resection.

Abstract: Objective To summarize the clinical characteristics of 35 patients with human monkeypox in Chengdu City, in order to provide theoretical basis for prevention and control of monkeypox epidemic in China. Methods A total of 35 patients diagnosed with monkeypox infection by Chengdu CDC from July 1 to July 23, 2023 were included in our study. The results of general clinical data, blood laboratory tests, lymph node ultrasound and chest CT results were collected in order to analyze the clinical features of human monkeypox patients in Chengdu City. Results All 35 monkeypox patients were young adult males, and there were no serious or fatal cases. Among them, 32 cases (91.4%) were men who have sex with men (MSM), and 30 cases had engaged in male-to-male sexual behavior within 21 days prior to the onset of the disease, of which 13 cases had taken protective measures. Fever symptoms were observed in 26 cases (74.3%) of the patients, with 19 cases experiencing fever within 1-6 days after the appearance of rash. The initial rash commonly occurred in the male external genitalia. Color ultrasound examinations indicated that all patients had swollen inguinal lymph nodes. C-reactive protein was elevated in 26 cases (74.3%) of patients, and 19 cases showed CD3+CD4+T/CD3+CD8+T< 1.0. 15 cases (42.8%) of the patients were infected with both monkeypox virus and HIV, 28.5% (10/35) of patients had concomitant skin infections and anorectal proctitis,respectively. The mean time from rash onset to the shedding of rash scabs was 14.8 days. Conclusions The MSM population in sexually active age group is the main infection object of human monkeypox virus. In monkeypox patients in Chengdu City, the rash starting at genital areas and rash occurring before systemic symptoms were common. Swollen inguinal lymph nodes are especially common in monkeypox patients. Skin infection and anorectal proctitis are the most common complications in monkeypox patients in Chengdu City. The abnormal cellular immune function in monkeypox patients is mainly reflected in the inverted ratio of CD3+CD4+T/CD3+CD8+T. Currently, there is no evidence to suggest that protective measures during male-to-male sexual behavior can reduce the risk of human monkeypox infection.

Objective To investigate the distribution and characteristics of iodine excess areas in Liaocheng City of Shandong Province, and to provide data evidence for taking intervention measures. Methods From 2011 to 2013, 1 - 3 samples of drinking water were collected from all administrative villages in 8 counties (cities and districts) of Liaocheng.At the same time,1 sample of edible salt was collected from the household where water samples were collected. Arsenic and cerium spectrophotometry was used for the detection of water iodine and salt iodine was detected by semi-quantitative method. The region were divide according to the definition of "Water Source Excess Iodine Area and Excess Iodine Disease Area"(GB/T 19380-2016)and"Division of Iodine Deficiency Disorders Area"(GB 16005-2009).Results A total of 7 794 water samples were collected in 5 865 villages of 134 towns and the iodine median was 158.2 μg/L. The median of water iodine of 57 samples was less than 10 μg/L in drinking water and the ratio was 0.7%;2 286 samples were 10- 100 μg/L and the ratio was 29.3%; 5 451 samples were over 100 μg/L and the ratio was 69.9%. The towns with suitable water iodine (10 - 100 μg/L) and high water iodine ( > 100 μg/L) were 24.6%(33/134)and 75.4%(101/134), respectively, and no iodine deficiency town was found. The areas with high water iodine were distributed in patchy or foci. A total of 3 300 salt samples were collected,among them,iodized salt was 1 183(35.58%,1 183/3 300)and non-iodized salt was 2 117(64.15%,2 117/3 300). Among them, there were 36 towns with high iodine content and 20 towns with suitable iodine content, and the iodized salt coverage rates were 10.72% (225/2 099) and 79.77% (958/1 201),respectively.Conclusions The population of Liaocheng City is at risk of iodine excess.The high iodine areas coexists with suitable iodine areas.

BACKGROUND: Chemotherapy is a common treatment for advanced hepatocellular carcinoma, but the effect is not satisfactory. The study aimed to retrospectively evaluate the effects of adding all-trans-retinoic acid (ATRA) to infusional fluorouracil, leucovorin, and oxaliplatin (FOLFOX4) for advanced hepatocellular carcinoma (HCC). METHODS: We extracted the data of patients with advanced HCC who underwent systemic chemotherapy using FOLFOX4 or ATRA plus FOLFOX4 at the Eastern Hepatobiliary Surgery Hospital, First Hospital of Jilin University, and Zhejiang Sian International Hospital and retrospectively compared for overall survival. The Cox proportional hazards model was used to calculate the hazard ratios for overall survival and disease progression after controlling for age, sex, and disease stage. RESULTS: From July 2013 to July 2018, 111 patients with HCC were included in this study. The median survival duration was 14.8 months in the ATRA plus FOLFOX4 group and 8.2 months in the FOLFOX4 only group ( P  < 0.001). The ATRA plus FOLFOX4 group had a significantly longer median time to progression compared with the FOLFOX4 group (3.6 months vs. 1.8 months, P  < 0.001). Hazard ratios for overall survival and disease progression were 0.465 (95% confidence interval: 0.298-0.726; P  = 0.001) and 0.474 (0.314-0.717; P  < 0.001) after adjusting for potential confounders, respectively. CONCLUSION ATRA plus FOLFOX4 significantly improves the overall survival and time to disease progression in patients with advanced HCC.
